If your Windows 10 system is slow and sluggish or if it’s severely infected with some troublesome virus, spyware, and malware that can’t be removed with the help of an anti-virus or anti-malware program, the only option you are left with is – format the Windows 10 OS. Full formatting – not quick formatting – removes all data from the Windows 10 hard drive including the viruses, malware, and spyware that are hidden deep inside the operating system.
However, this is not the only scenario where you need to format Windows. Before selling your Windows 10 powered laptop, PC, or the hard drives, it’s important that all your personal files and folders including programs and software files you used are permanently erased from the system or the drive to ensure privacy and protect yourself from data theft and data leakage.
You can either choose to delete data by formatting the partitions on your Windows 10 PC via Disk Management tool and system repair disc or use a data erasure tool that destroys data permanently beyond the scope of data recovery.
But first, let’s learn why you should always erase data – not just format or delete – for better data protection and privacy.
Format Vs Erase
Quick format, which is most commonly used format option, deletes access to the files that are stored in the drive. As a result, the deleted files after format still remains on the same drive or volume unless overwritten. Normal format removes the old file system and creates a new one but the data can still be easily recovered from such hard drives.
Erase makes data recovery impossible as it writes a pattern of 1’s and 0’s on the entire hard drive or where data was stored. Wiping and Scrubbing are two techniques that are used for erasing data. Wiping wipes the entire drive or volume including empty space containing previously deleted files and folders.
If you want to remove virus and malware or going to use the same system (or hard drive) after reinstalling Windows or any other OS, you can use Disk management tool or a system repair disc to format Windows 10. Follow these steps to format non-system hard drive volumes or disk using Disk Management:
However, recovery of data from a formatted (& re-formatted) volume or hard drive is an easy task with the help of a clever data recovery tool.
To format Windows 10 drive (C:), you need a system repair disc and boot the system via the repair disc.
In case you are going to sell your PC or hard drives, erasing the data is the best way to safeguard privacy and protect data from theft and leakage. Erased data using a free wipe or shredder tool can still be recovered with the help of forensic tools or sophisticated data recovery software as they follow a basic pattern to fill drive with 0’s and 1’s. To make data recovery impossible, you need to use a powerful tool such as BitRaser for File that uses 17 international data erasure standards (algorithms) like NATO, U.S. Department of Defense (DoD 5220.22-M) 3 pass/7pass, etc. to erase files and folders or data from the entire volume beyond the scope of data recovery.
Follow these steps to securely erase Windows 10 without CD using BitRaser for File:
BitRaser for File removes every bit of data from the hard drive beyond recovery. This also removes all those annoying malware and virus from the hard drive.
Never sell or donate your PC, laptop, or other storage devices without executing proper data sanitization. To safeguard your privacy and ensure data protection, use effective data erasure tool like the one we mentioned in this post. Free eraser and wipe tools just work but aren’t effective at erasing data that cannot be recovered since they follow a standard pattern of writing 1’s and 0’s. Whereas BitRaser for File uses 17 different algorithms – many of them with multiple passes – to ensure data is sanitized accurately.
